Sikkens products are known throughout the industry for offering unrivaled looks, durability, and performance for all types of wood.

Cetol Log and Siding provides a high performance, translucent, satin finish for vertical surfaces. This alkyd high solids formulation offers optimum protection and a premium look in just two coats. The high solids alkyd resin used in Sikkens Log and Siding is another example of the advancements central to Sikkens “Next Wave” technology.

WHAT IS CETOL LOG & SIDING?

Cetol Log and Siding’s two coat satin finish creates a protective film which gives siding and logs a premium furniture look while still allowing the natural character and grain of the wood to show through. The product creates a durable surface barrier to prevent wood from weathering.

WITH CETOL LOG AND SIDING LOG MOISTURE CONTENT BELOW 18% IS THE KEY!

Laminated logs: Generally the moisture content of laminated logs is below 14% and they are ready for immediate application of Cetol Log and Siding once they have been cleaned.

Kiln-dried or air dried logs: Generally, the moisture content of these logs is below 18%; however, some logs may have a moisture content higher than 18%. Therefore, it is recommended to apply Sikkens Log Pretreatment and then allow a 6 month drying period before applying Cetol Log & Siding.

Green, wet, or treated logs: These logs have a moisture content greater than 18%. Therefore, it is recommended to apply Sikkens Log Pretreatment and allow a 1 year drying period before applying Cetol Log & Siding.

When Cetol Log and Siding is applied to logs that have over an 18% moisture content, mold and mildew can grow beneath the surface of the coating. Also, as the moisture attempts to escape, it can cause Cetol Log and Siding to lift or peel. When in doubt about moisture content, use a moisture meter to make certain the moisture content is below 18% prior to Cetol Log and Siding Application.

HOW SHOULD LOGS BE TREATED ONCE THE LOG HOME IS ERECTED?

1. Clean mud and dirt off logs with a pressure washer.
   
2. Unless your logs have been pretreated with borate at the factory, we recommend applying an EPA registered borate wood preservative treatment such as Shellguard as soon as possible according to the preservative manufacturer recommendations.
   
3. When your log surface is dry brush off any residue from the borates and spray one light coat of Sikkens Log Pre-Treatment on the outside of your logs. This prevents further moisture absorption and protects the logs while the home is under construction. It also allows for a six (6) month drying period to ensure all the logs are below 18% moisture content.
   

WHAT IS THE BEST WAY TO CLEAN YOUR LOGS PRIOR TO APPLYING CETOL LOG AND SIDING FINISH?

1. Spray the surface with clean water, wetting the wood.
   
2. Clean the surface with a solution of 4 ounces of 100% powdered Tri-Sodium Phosphate (TSP) or phosphate-free substitute plus, 1 quart of liquid bleach in 3 quarts of water. Apply this solution generously to the wood with a garden pump sprayer.
   
3. Let the solution sit on the wood for 15-20 minutes. During this period, scrub the surface with a hard bristle brush to help remove mill glaze and/or weathering. Do not let the solution dry on the wood. Keep it wet.
   
4. Power wash the cleaning solution from the wood with clean water. To prevent damaging the wood, do not exceed 500 psi. The nozzle must be a maximum of 1 foot from the surface for full effectiveness.
   
5. Let surface dry for 3 dry days before application (i.e. the moisture content is below 18%).
   
6. You are now ready to apply Sikkens Cetol Log and Siding. Apply two (2)
   coats of Cetol Log and Siding within four (4) weeks of cleaning the exterior
   logs.

SPECIAL APPLICATION TIPS

• It is always recommended to perform a two coat color test on a sample of your wood. Cetol Log and Siding is difficult to remove once it has been applied. Before doing a full application make sure that your color selection is correct.
• New Rough-sawn wood should be dry-brushed using a brush with stiff bristles to remove loose dirt and fibers, if debris is still present, then follow the preparation procedures.
• Weathered wood affected with blue fungi or rust from nails may be treated after the surface preparation by applying a solution of 4 ounces of oxalic acid crystals in a gallon of warm water. This solution should be allowed to sit on the affected areas for 15-20 minutes before the final rinse with clean water. Let dry 3 days before coating.
• Fill all joints, cracks, and nail holes with a good quality polyurethane or acrylic caulk/filler prior to applying the coating.

2. Examine caulking at corners, butt joints, windows and doors and fill any voids with Energy Seal or Super Caulk.
3. Clean any areas where dirt, residue, etc. may be accumulating on the logs because of splash back around decks, foundations, or dormers. Clean with a mild detergent such as Logwash. Keep the solution wet on the surface of the logs for about 15-20 minutes and rinse well with a garden hose.
4. A little maintenance goes a long way in keeping your logs and siding beautiful.
